You didn't mention your spindles, but is it possible you have one of the goofy '41 Ford "roundback" spindles like the one pictured below, which has it's drag link hole tapered from the top.......instead of tapered from the bottom like ALL '37-'40 "roundbacks"?
Lots of folks don't believe there are '41 roundbacks like this, but they awkwardly require the drag link to be installed on the top side, which could easily cause your drag link to hit the wishbone. DD
